TEST LEADS Before each measurement always assure that the
calibration is for the cables in use. During a
continuity test, if the resistance value free of
calibration (that is the resistance value less the
calibration offset value) is negative, the symbol
ν
is displayed. Probably the calibration resistance
value stored in the instrument memory is not for
the cables in use, therefore a new calibration must
be performed.

FUNC CAL
To cancel calibration
parameters it is
necessary to perform a
calibration procedure
with a resistance of
test leads higher than
5
Ω (for example with
open test leads). When
a cancellation is effected
the screen to the right
is displayed temporarily.
